Going to the dentist soon (hopefully). How long do you think it will take to fix my teeth?

So, hopefully around September I can finally get myself into a dentist. I stopped going to the dental school because it was just taking TOO LONG and was stressing me out and I was missing sooooo much school. Anyway, so far, I have around 16 cavities. I had a root canal started, but I'm not sure how far they got (it took like 5 visits) I am missing half at that tooth now because the temporary filling fell out and I chipped it while eating cereal the other night. I also have a back tooth that is chipped. I am 16 and I went to the dentist a year ago, I think. I'm really hoping I can get to one in September, or sooner if I can find a dentist that will take me (I have Medicaid and there aren't a lot of dentists that will take me). About how many visits do you think it will take for them to fix my teeth? I just want to get this over with. It's sooo stressful. How many fillings can they do at a time? I don't think Medicaid covers crown and I know I'm going to need 1 at least probably. My dad doesn't make a lot of money. Are most dentists able to work out payment plans for poor people? We can't afford dental insurance.
